Non-Planar GPS Receiving Antenna Navy STTR FY2005 Sol No.: Navy STTR FY2005 Topic No.: N05-T002 Topic Title: Non-Planar GPS Receiving Antenna Proposal No.: N054-002-0199 Firm: Applied EM Inc. 144 Research Drive Hampton, Virginia 23666 Contact: C. Reddy Phone: (757) 224-2035 Web Site: www.appliedem.com Abstract: Providing accurate PVT (Position, Velocity and Time) information is very critical for systems like Joint Precision Approach and Landing System (JPALS). JPALS is a key component enabling U.S. military forces to be highly mobile and capable of "rapid response" on a global basis to a wide range of military scenarios. JPALS must remain operational throughout a range of threat environments, and with performance requirements tailored to supporting a highly mobile force at all locations, including an austere forward operating area worldwide. In addition of the weak signal power from GPS satellites, JPALS-equipped aircraft are expected to operate in the presence of significant radio frequency interference (RFI) and low elevation look angles of GPS satellites. To address this issue, Applied EM is proposing an innovative non-planar GPS antenna array solution with advanced adaptive signal processing techniques. This novel design will provide anti-jamming protection against low elevation angle jammers and maintain reception at the same time to provide highly accurate navigation results. Benefits: The proposed non-planar anti-jam antenna system is based on a systematic theoretical and experimental program. Since our research effort will emphasize low cost product development without sacrificing RF performance, it will be highly suited for commercialization. This technology has applications in many commercial uses such as rental car, personal navigation system and cell phones. Return
